Using this wiring harness is easy. First, make sure your vehicle is turned off to avoid any electrical issues. Locate the worn or damaged fog light wiring harness on either the passenger or driver side at the front of your 2015 - 2021 Subaru WRX or STI. Carefully remove the old harness and connect the new one to the fog lamps and turn signal lamps. When installing, double - check the connections to ensure they are secure. As for maintenance, keep the harness clean and dry. Avoid exposing it to excessive moisture or sharp objects that could damage the wires. If you notice any signs of wear or damage after installation, replace it promptly to keep your fog lights working properly.
